What this tool calculates
Project compounded bankroll growth from a starting balance, expected return per period, and number of periods while showing absolute change.
Projected bankroll = starting bankroll × (1 + return rate per period) ^ number of periods.
Inputs are processed locally in your browser. Verify market definitions and settlement terms before relying on a result.
Worked example
Starting with 1,000 and compounding 2% for 12 periods gives about 1,268.24, an increase of roughly 268.24.

FAQ
How is the bankroll growth calculated?
Projected bankroll = starting bankroll × (1 + return rate per period) ^ number of periods.
Does the result include bookmaker margin?
Only when the displayed formula explicitly uses market odds. Model probabilities and projections are based solely on the values entered.
Why can my bookmaker settlement differ?
Operators may use different rounding, void, dead-heat, minimum-stake, or market settlement rules. Check the rules for the specific bet.
How much precision does the calculator use?
Calculations use JavaScript floating-point precision and are rounded only for display, normally to two or four decimal places.
Can this result predict a winning bet?
No. It calculates a mathematical scenario from your inputs and does not account for every source of uncertainty or guarantee an outcome.
